Video: Tributes have been paid to Saman Kunan, a former navy Seal diver who died in the attempted rescue of a group of Thai boys trapped in a cave. His body has been taken aboard a C-120 plane to Bangkok and he will receive a royal-sponsored funeral in the coming days. The former Seal died at about 1am on Friday when he ran out of oxygen on his way back to the surface after placing air tanks along the two-mile route to the boys, the current method for refreshing the air supply in the cave.
